I have a control that handles commenting. In this control, I have set a delegate event handler for sending an email.

I then have various types of controls, e.g. blog, articles etc, each of which may or may not have the commenting control added (which is done dynamically with me not knowing the id's), i.e. the commenting control is added outside this control. Each of these controls handles it's emailing differently(hence the event).

What I'm trying to determine, is how to assign the event in the parent control. At the moment, I'm having to recursively search through all the controls on the page until I find the comment control, and set it that way. Example below explains:

COMMENTING CONTROL

public delegate void Commenting_OnSendEmail();

public partial class Commenting : UserControl
{
   public Commenting_OnSendEmail OnComment_SendEmail();

   private void Page_Load(object sender, EventArgs e)
   {
      if(OnComment_SendEmail != null)
      {
          OnComment_SendEmail();
      }
   }
}

PARENT CONTROL

public partial class Blog : UserControl
{
   private void Page_Load(object sender, EventArgs e)
   {
      Commenting comControl = (Commenting)this.FindControl<Commenting>(this);
      if(comControl != null)
      {
         comCtrol.OnComment_SendEmail += new Commenting_OnSendMail(Blog_Comment_OnSendEmail);
      }
   }
}

Is there an easier way?
